Hi suman, how did you model the curled up belt that you are showing there with the rotation arrow around it, was it done using sweep or something like that?

Or are you using curve-to-curve flow for the result that you show there?

If you are using curve-to-curve flow and the twisting of the result is not what you want, you may want to instead construct a sort of ribbon surface using something like Sweep - to do that you would draw in a line along your path and use Construct > Sweep to generate your target surface, then draw a base plane underneath your starting shape and use surface to surface Flow for deforming the belt (that's where you select a base surface and a target surface rather than curves), and you can rotate the line before doing the sweep to control the twisting.

It could be easier to help you if you would post a 3DM model file with your current results in it, that would make it easier to understand what you're currently doing.
